Energy from waste heat: how thermoelectric materials are designed and used
Recent advancements in thermoelectric materials involving nanostructuring semiconductors have create large excitement and highlighted the technology’s potential for energy efficiency and heat management on a commercial scale. Nanostructuring is the process of embedding suitable second phase, in nanocrystalline form, inside a thermoelectric material. This process dramatically lowers the thermal conductivity of the composite and greatly enhances the conversion efficiency. Waste-heat recovery with thermoelectric power generators can improve energy efficiency and provide distributed electricity generation. Energy-intensive industries, such as cement making, glass making, coal-fired power plants and metals production, generate enormous amounts of heat, and most of this heat is lost into the environment through smoke stacks and other means. Thermoelectric devices are very attractive because they convert thermal energy into electricity without requiring moving components. Current research in high performance thermoelectric materials involves nanostructuring, mesostructuring, band alignment, band engineering and other concepts. These are synergistic strategies for boosting the thermoelectric performance. To date, the dramatic enhancements in figure of merit achieved

Franck ARTZNER est responsable du groupe «auto-assemblages bio-inspirés» qui s’intéresse à des matériaux variés allant de la fibrillation des peptides pharmaceutiques à la cristallisation des colloïdes. Son groupe possède une expertise de l’analyse des structures par diffusion de rayons X non conventionnelle (SAXS, Diffraction de fibres). Il dirige le Laboratoire Commun avec IPSEN, Archi-Pex, qui étudie la formulation commerciale de peptides auto-assemblés. Il a été le l’animateur du groupe sur les Nanotechnologies Bio-inspirées à l’OMNT. Il a reçu le prix Delalande de l’académie Française de pharmacie en 2016.
Détourner des auto-assemblages biologiques pour synthétiser des matériaux hiérarchiques?
La synthèse de matériaux hiérarchiques, se fabriquant spontanément avec une précision ultime et sachant s’adapter au milieu, est une des spécificités des structures biologiques. Ces mécanismes naturels d’auto-assemblages peuvent être détournés en chimie pour imaginer de nouvelles stratégies de synthèse : la fabrication de matériaux organisés hiérarchiquement du nanomètre au centimètre est peut ainsi être réalisée en couplant des gradients macroscopiques de concentration 1,2 ou de pression3 avec des interactions intermoléculaires entre des composants inorganiques et des auto-assemblages biologiques. Dans le cadre de systèmes simplifiés formant des nanotubes, il est aussi possible de contrôler le diamètre entre 9 et 35 nanomètres par mutation chimique,4 et, de moduler le diamètre grâce au pH entre 10 et 50 nm.5 Un de ces auto-assemblages biomimétiques est utilisé en délivrance contrôlée d’un principe actif dans de nombreux pays (AMM, FDA,…).

MoS2 and its Cousins : 2D Materials with Promising Optical Properties
The spectacular progress in controlling the electronic properties of graphene has triggered research in alternative atomically thin two-dimensional crystals. Monolayers of transition-metal dichalcogenides such as MoS2 have emerged as very promising nanostructures for optical and electronic applications. In this talk I will give an overview of the physical properties of 2D semiconductors based on transition metal dichalcogenides : band structure, exciton effects, optical and transport properties, and spin/valley dynamics. Prototype devices based on these 2D materials will also be presented (LED, Photo-detector, …).

Jean-Philippe ANSERMETDirecteur de Recherche CNRSITODYS UMR 7086, Univ. Paris Diderot15 rue J.A. de Baif, F-75013 Parishttp://[email protected]
Jean-Philippe Ansermet was born March 1, 1957 in Lausanne (legal origin Vaumarcus, NE). He obtained a diploma as physics engineer of EPFL in 1980. He went on to get a PhD from the University of Illinois at Urbana-Champaign where, from 1985 to 1987, he persued as post-doc with Prof. Slichter his research on catalysis by solid state NMR studies of molecules bound to the surface of catalysts. From 1987 to 1992 he worked at the materials research center of Ciba-Geigy, on polymers for microelectronics, composites, dielectrics and organic charge transfer complexes. In March 1992, as professor of experimental physics, he developed a laboratory on the theme of nanostructured materials and turned full professor in 1995. Since 1992, he teaches classical mechanics, first to future engineering students, since 2004 to physics majors. Since 2000, he teaches thermodynamics also, to the same group of students. He offers a graduate course in spintronics, and another on spin dynamics. His research activities concern the fabrication and properties of magnetic nanostructures produced by electrodeposition. His involvement since the early days of spintronics have allowed him to gain recognition for his work on giant magnetoresistance (CPP-GMR), magnetic relaxation of single nanostructures, and was among the leading groups demonstrating magnetization reversal by spin-polarized currents. Furthermore, his group uses nuclear magnetic resonance , on the one hand as means of investigation of surfaces and electrodes, on the other hand, as a local probe of the electronic properties of complex ferromagnetic oxides.
SPINTRONICS : From front line research to discovery
My lab has used electrochemistry as a means of growing nanowires, starting in 1992. Thanks to this technique, we were among the first to measure giant magnetoresistance with an electric current running perpendicular to Cu and Co layers. We were second worldwide in demonstrating the theoretical prediction according to which a spin current can flip magnetization. This work culminated in the demonstration (ref. a of the list below) that we could produce by electrodeposition spin torque oscillators that generated signals at about 5 GHz.
13
We ventured into developing a 3-current model that added a heat current to the two-currentmodel of Mott; a model well known in the magnetoresistance community. Many followed us, as attests the relatively often-cited paper in which the validity of our model was tested on an original magneto-transport measurement, which we coined the “Magneto-Thermo-Galvanic-Voltage” (ref. b). In 2008, Prof. G. Bauer launched the field of “spin caloritronics” based on results such as ours. I
n 2010, we were the first to demonstrate that a heat current can induce a spin current in a metallic ferromagnet (ref. c). The experiment was inspired by a theoretical prediction of Prof. Bauer et al. Our 3- current model could account for our data on the effect of heat current on magnetization switching, whereas the theory of that seminal paper could not. It was only in 2014 and 2015 that three groups (Parkin, Koopmans, Cahill) confirmed the existence of a coupling of heat and magnetization dynamics in metallic ferromagnets, using far more complicated experimental means.
In 2010, we engaged in a revision of the thermodynamics of continuous media, in which we included electromagnetic fields as state variables, not simply as fields imposed to the system. This led us to predict an effect we called the magnetic Seebeck effect. Our theory predicts that a magnetic field is induced by a temperature gradient, just like in the Seebeck effect, an electric field is induced by a temperature gradient. We predicted that a magnetization wave propagating from a cold to a hot zone would be less dampened than if it propagated in the same sample at a uniform temperature. We verified the effect (ref. d). This work constitutes a discovery, as both the theory and its experimental demonstration stem from our group.

Jérôme Pélisse, Professor of Sociology at Sciences Po Paris, member of the Center for Sociology of Organizations (CNRS). He analyses various topics at the crossroads of sociology of labor and sociology of law, notably the transformations of industrial relations and regulations of working time and health and safety politics at work. He also studied the interactions between science and law, through the analyze of judicial expertise and experts in France or the management of risks in nanolabs in France and United States. He notably published Droit et régulations des activités économiques : Perspectives sociologiques et institutionnalistes (with Bessy and Delpeuch), LGDJ-Lextenso, 2011 and « Ca sent bizarre ici ! La sécurité dans les laboratoires de nanomédecine », Sociologie du travail (to be published in 2017, with Céline Borelle).
Before or in the lab? Safety practises and management in nanolabs in France and US
This communication will present a research on safety in various scientific laboratories specialized in nanoscience, in France and US. Based on an ongoing research grounded in ethnographic methods and interviews with various actors (researchers, students, principal investigators, safety representatives, environmental, health and safety officers) in five labs specialized in nanomedicine or chemistry, it aims at proposing results on the implementation of safety regulations in scientific organizations. The France-US comparison is first used to underline the variety of safety regulations adopted at different levels: European Union and US Federal regulations, but also state or sometimes municipal institutions, and obviously universities and the labs themselves.
Nevertheless, the uncertainty related to nanoparticles and nanomaterials opens controversies at these different levels and notably into the labs, between the internal scientific knowledge and the external regulations implemented by environment, health and safety offices. The communication will thus evoke the implementation of these more or less specific regulations and the interactions between the researchers and specialized actors in safety working into the labs or outside to understand the safety cultures in daily scientific practices in nanolabs.
Key words : safety, nanoscience, regulations, ethnography

NMI: Atomic-Scale Imaging and Site-Specific Chemical Analysis with Transmission Elec-tron Microscopy: In-Situ and Operando Techniques
The transmission electron microscope (TEM) was originally developed in 1930’s to image biomaterials with high resolution, though the damage produced by the electron beam and the high vacuum environment prevented quantitative imaging of these materials in-situ until recent years. This presentation will cover the capabilities of the transmission electron microscope with a particular emphasis on in-situ methods for understanding the materials’ structure-property relationship (environmental, mechanical, electrical, and magnetic property measurements). High-resolution TEM characterization is critical to nanoscience, in terms of defining materials synthesized, chemical mapping throughout the structures and the physical properties of the materials. Advanced TEM techniques including aberration-correction for high spatial resolution, dynamic and stroboscopic techniques for high temporal resolution and the development of direct electron detectors have expanded the functionality of standard TEM imaging. These capabilities will be described in reference to nanoscience applications that can benefit from them. My work has focused on imaging materials within a continuous liquid, therefore many of the examples will cover these methods to determine the structure and processes of materials in operational environments. Finally, I will comment on new developing techniques and instrumentation for nanoscale characterization with the TEM.

NSW: In-Situ TEM of Energy Storage Materials (Li-Ion Batteries) and Corrosion Mechanisms
Nanoscale materials for energy storage are of interest for their high surface-area-to-volume ratio that can translate to fast ion conduction for rapid charge transfer, meaning operation of batteries at higher charge and discharge rates. Therefore, the TEM provides a unique test-platform for the study of structural changes in materials under charge cycling to understand the multifaceted reactions occurring at electrode-electrolyte interfaces within standard batteries. This presentation will cover Sandia’s use of open-cell and closed-cell cycling of battery electrodes in the TEM, with a particular emphasis on understanding Li metal anodes from early nucleation and growth behaviour. Viewing battery systems at high resolution provides the ability to watch several processes occurring simultaneously, including corrosion processes that may be overlooked on a larger scale. In regard to new techniques, this presentation will cover our methods for introducing temperature control into the electrochemcial TEM cell and strategies for integrating designer nanomaterial electrode materials into the TEM test platform.
Key words : Transmission Electron Microscopy, Li-Ion Energy Storage, Corrosion, Solid-Li-quid Interfaces, Nanoparticle Nucleation and Growth, and Nanoassemblies

Angela VELLAAngela VellaProfessor - GPM Université de Rouen NormandieAvenue de L’université 76801 Saint Etienne du Rouvray, FRANCE Email : [email protected]
Angela VELLA obtained her PhD at the University FERERICO II in Naples on non linear optics. After a post doc at the University of Montpellier and at the Ecole Normale Supérieure de Cachan, she was recruited in 2005 at the University of Rouen where she joined the instrumentation team as assistant professor in the Groupe de Physique des Matériaux (GPM). She has been involved in the pioneer work on the development of the atom probe tomography laser assisted by ultrafast laser pulses. Her work covers fundamentals of the field emission and laser-matter interaction as well as the application of the technique to non-metallic materials such as oxides. She recently demonstrated the new capabilities of the APT as an investigation tool of thermal and optical properties of materials at the nanometer scale.
The laser assisted atom probe tomography: a new investigation tool of thermal and optical properties of nano-materials.
Many techniques of materials analysis or materials structuring are based on the interaction of a light source with the apex of a sharp metallic tip with subwavelength dimensions. The field enhancement phenomenon occurring at the apex can be used to make nanotweezers or to generate a localized excitation on the surface of a planar substrate or to nanostructure this surface [1]. In this presentation, we will show that the laser assisted atom probe tomography (La-APT) can be used as an original setup to study the interaction of ultra short laser pulses with a nanometric tip. In laser assisted APT, an ultra short laser pulse is used to trigger the field ion evaporation from a sharp tip [3]. The laser intensities usually used for APL analysis are in the range between the ones used for nanostructuring and the ones used for near field image of materials or in photo assisted field-electron (FE) emission.
18
By La-APTWe, we can study the optical properties of nano tips (metallic and insulating) and, in particular, in the case of metallic nano tip, we reported the self-confinement of absorption at the end of the tip and, by varying the direction of the laser electric field, a condition of resonant excitation of plasmons surface polariton of the hemisphere which teminates the tip. On non-metallic samples, we observed the change of the optical absorption of the surface under high electric DC field. Moreover, we studied the change of emission properties of nano-emitters contening color centers under high DC field, coupling La-APT with micro-photoluminescent analysis in-situ.
Key words : laser assisted field emission and evaporation.

Mélanie AUFFANCR-CNRSCEREGEEuropole de l’arbois 13545 Aix en Provencehttp://[email protected]
Melanie Auffan is a CNRS research scientist at the CEREGE in Aix en Provence. She is member of the steering committees of iCEINT ‘international consortium for the Environmental Implications of Nanotechnology’ and CEINT ‘Center for the Environmental Implications of Nanotechnology’. Her research addresses the physico- chemical properties and surface reactivity of nanoparticles in contact with living organisms. Since 2012 she is part of the safer by design project called Labex Serenade (Laboratory of Excellence for Safe(r) Ecodesign Research and Education applied to NAnomaterial DEvelopment).
Indoor mesocosms: an integrated approach to assess the environmental risks of nanomaterials Headway has been made in exploring the potential impacts of engineered nanomaterials (ENMs) on human health. However, investigation of the roles of nano-scale objects towards evolutionary change, environmental disturbance, ecosystem structure and function have lagged behind the advances in fabricating, measuring and manipulating materials at the nano-scale. Moreover, current approaches to assess the ENMs environmental safety are based on classical ecotoxicology approaches, which are not always adequate for ENMs. For instance, most of the research only concerns the hazard but rarely the exposure to ENMs that plays a pivotal role to understand their environmental risks. The exposure depends on various properties; some of them are those of colloids (e.g. hetero-, homo-aggregation, adsorption of organic matter), while others are characteristic of nano-size (e.g. redox transformation, dissolution and ubiquist mineralogy).
We will present an innovative design offering physico-chemists, (micro)biologists, and ecologists the possibility of conceiving robust experiments to study the exposure and impacts of engineered nanomaterials as well as mechanistic concepts at various time and spatial scales. This system is based on modular, intermediate size (60 L), indoor aquatic mesocosms (Auffan et al. 2014). It is adjustable to several ecosystems as lothic, lentic, estuarine, or lagoon environments (Tella et al. 2014, Tella et al. 2015).
Key words : Mesocosms, realistic exposure condition, ecotoxicology, nanomaterials ecosys-tems.

In 2009 I received a PhD from Swinburne University of Technology in Melbourne, Australia, where I studied the application of plasmonic nanoparticles in optical data storage. After a postdoctoral fellowship in Leiden I am now employed at Eindhoven Universit of Technology. My mission is to develop approaches for single-molecule sensing with the aim to study individual biomolecules in complex environments. We combine concepts from single-molecule microscopy, plasmonics, and biochemistry to study the properties and interactions of biomolecules at the single-molecule level.
Quantification of biomolecular interactions at the single-molecule level has greatly expanded the scope of biosensors and analytical technologies. In contrast to ensemble-averaged approaches, single-molecule sensitivity gives access to the underlying heterogeneity of molecular properties. This heterogeneity could originate from e.g. the presence of different species within a sample, or the presence of different conformations of the same species.
Most single-molecule techniques exploit fluorescence, which was first reported in the early 1990s. However, fluorescent labelling is not feasible in biosensing applications where measurements are conducted directly in a biological fluid with no washing steps. This has sparked efforts to achieve so-called “label-free” single-molecule sensors that do not require fluorescent labelling to generate a signal. Recently, plasmonic sensors based on individual metallic nanoparticles (mostly gold) have reached the single-molecule regime, which is the focus of this presentation.
The ability to detect single molecules using plasmons is facilitated by the electric field associated with the plasmon resonance. This field penetrates the medium around the particle and enhances the interaction between a molecule and the plasmon resonance. This plasmon-molecule interaction provides two pathways for sensing, namely (1) by exploiting the effect of the plasmon on the molecule leading to modification of the molecule’s radiative properties, or (2) by exploiting the effect of the molecule on the plasmon leading to frequency shifts of the plasmon resonance. I will describe both mechanisms for sensing, and discuss potential applications of plasmon-enhanced single-molecule sensors.

Ralf Jungmann studied Physics at Saarland University, followed by a one-year diploma research stay with Paul Hansma at UC Santa Barbara where he worked on functional imaging of bone ultrastructure using Atomic Force Microscopy and High-Speed-Photography. In 2007, Jungmann joined Prof. Friedrich C. Simmel’s lab at TU München as a Ph.D. student and was among the first researchers in Germany to apply and extend the DNA origami technique. During his Ph.D., Jungmann applied single-molecule fluorescence techniques to DNA Nanotechnology, constructing the first nanoscopic DNA origami “rulers” for super-resolution microscopy. He also pioneered a novel type of super-resolution microscopy, termed DNA-PAINT, that uses programmable DNA molecules as imaging probes.
After receiving his Ph.D. at TUM, he moved to the labs of Prof. Peng Yin and Prof. William M. Shih at the Wyss Institute for Biologically Inspired Engineering at Harvard University as an Alexander von Humboldt fellow. At Harvard, Jungmann worked on applications of DNA-PAINT for multiplexed cellular imaging.
In 2014, Jungmann received an Emmy Noether Fellowship from the German Research Foundation (DFG) and since then heads the research group “Molecular Imaging and Bionanotechnology” at the MPI of Biochemistry and the LMU Munich. In 2015, Jungmann co-founded Ultivue, a US-based company commercializing imaging reagents for DNA-PAINT super-resolution microscopy.
In 2016 he received an ERC Starting Grant to bring DNA-based super-resolution imaging from single molecules to whole cells and tissues. Since August 2016, he is Professor of Physics at the LMU Munich.

He authored around 50 publications and 7 patents.Soft-Chemistry meets Soft-Lithography: From Chemical Solutions to Photonic and Nanofluidic Devices“Soft-chemistry” approaches (based on self-assembly, sol-gel chemistry, coordination chemistry...) allows periodical assembly the matter at the sub 100 nm scales into nanostructured materials with a great control in term of dimensionality, periodicity and composition. Complex patterns at the micro/nanometric scale can also be achieved by all the so-called “soft-lithography” approaches that consist in molding the material through an elastomeric stamp. In this talk I will describe our initiative in integrating functional nanoporous materials (MOFs and mesoporous sol-gel materials and films) into real devices by combining soft-chemistry and soft-lithography (Figure a).1
The main processing steps (liquid deposition, pattering, self assembly) will be first introduced. Applications of these systems in photonics and nanofluidics will be described later-on. Porous photonic sensing platforms (1D, 2D photonic crystals, graded materials,2 diffraction gratings) were developed for the easy-detection of toxic compounds by smart phone (Figure b).3,4 Sol-gel based nanopillared/nanofluidic channels were also fabricated to induce and study chemical reactions (nanoparticles formation or air-liquid biphasic reactions) and dew formation in nanoconfined environments (as shown in the Figure c).4,5

Communication and cooperation: Transdisciplinary approaches for a safe material design
Research institutes and start-up enterprises that develop nanomaterials and other advanced materials often have insufficient knowledge available regarding questions related to chemical safety and the risks for man and the environment. First empirical findings in the field of governance studies indicate that collaboration among scientists, regulators, and representatives from industry can contribute to the effective co-regulation of nanomaterials safety if set up and coordinated based on certain criteria. Against this backdrop, BAuA is developing a concept for a support structure for start-ups and research institutes by which learning on various levels on the safety of chemicals among the collaborators is initiated and guided. The development of chemicals based on application safety principles is furthered. Drawing on the lessons learned from the collaboration process policy advice can be formulated as to how innovation processes in material science within small research institutes can be supported.

Basics of nanomagnetism for memories Since the founding discovery of giant magnetoresistance in 1988, a chain of scientific and technology breakthroughs has led spin electronics to a new paradigm. There are now efficient ways to monitor electrically the magnetization of a nanodevice by magneto-resistive effects, while the spin angular momentum transfer effects allow the control of the magnetization dynamics through bipolar current in nanodevices.
The first broad application of spin electronics came as soon as 1997 with the spin valve read head for magnetic hard disk, revolutionizing this recording technology through the fast increase in recording density it triggered. Since then, a wealth of magnetic sensors was developed for transport, MEMS, biomedical issues, etc. And the more recent breakthroughs generated a spectacular acceleration towards integration of magnetic devices into solid-state electronics such as magnetic memories or M-RAM (commercialized since 2007), and more recently to non-volatile programmable logic chips. The lecture aims to give a broad overview of the area, based on basic principles ofmagnetism and spin electronics.

Christophe Drouet is a French CNRS Researcher. Leader of the “Phosphates, Pharmacotechnics, Biomaterials” (PPB) group at the CIRIMAT Institute, University of Toulouse, France. Ph.D. in Materials Sciences, and former Research Associate in Prof. A. Navrotsky’s group at UC Davis, USA. A special focus in C. Drouet’s research is dedicated to the investigation of the physico- and thermo- chemistry of calcium phosphates and related compounds. This involves in particular the study of biomimetic nanocrystalline apatites analogous to bone mineral, in view of biomedical applications (bioactive multifunctional bone-repair materials, colloidal nanoparticles for nanomedicine...) and for a better understanding of biomineralization and bone diagenesis processes. C. Drouet received in 2013 the “Racquel Legeros Award”, and in 2016 the “Excellence Award” from the International Society for Ceramics in Medicine (ISCM), for contribution to the field of calcium phosphate research.
Biomineralization: the case of apatites... and medical applications of biomimetic analogs Biominerals are key compounds for many living organisms. In Vertebrates, calcium phosphate apatites represent about 70% in weight of skeletal matter. Interestingly, the apatite structure is very accommodating, allowing a variety of ionic substituants and a large departure from stoichiometry – as opposed to silica or calcium carbonate found in more primitive organisms. The physicochemical characteristics of apatitic biominerals can then allow adaptation to different functions in vivo. While tooth enamel (consisting of coarse-grained hydroxyapatite close to stoichiometry) has to resist acidic attacks from bacterial activity, bone mineral (i.e. nonstoichiometric and polysubstituted nanocrystalline apatite) should easily undergo bone resorption for microfractures self-healing and skeletal development, and needs to exhibit a high surface reactivity for interacting with surrounding body fluids components (homeostasis).

In this seminar, the composition of bones and teeth will be reminded. Then, the specific characteristics of apatite nanocrystals composing bone mineral as well as synthetic biomimetic analogs will be described and commented, both from a physicochemical and thermodynamic point of view. In a more applied domain, the exceptional reactivity of apatite nanocrystals can be exploited by way of ionic exchanges and molecular adsorption, for tailoring the properties of (multi)functional advanced biomaterials. In this presentation, these aspects will also be developed and illustrated in link with applicative domains like regenerative medicine (e.g. bone regeneration) and, in a more innovative way, in nanomedicine (e.g. oncology, dermatology...).

Super-resolution optical imaging of electrochemical processes
World’s demand for renewable and sustainable sources of energy has drastically escalated during the past few decades. Manmade nanomaterial catalysts are still far from meeting the requirements for clean energy production. Therefore it is crucial to develop new nano-catalysts and high performance techniques to study them in operando.Within the last decade, powerful electroanalytical strategies have been proposed, based on the time-resolved detection of stochastic electrochemical collisions of individual nanoparticles, (NPs) on ultramicroelectrodes[1,2a] or the control of NP electrochemistry at nanoelectrodes. Such pure electrochemical strategies provide much valuable information concerning NP electrochemistry, size or concentration, they are however blind to a wide range of information. Few groups,[2] including ours, have proposed the coupling of different optical microscopies to the electrochemical activation as promising platform for in situ imaging of chemical processes at the micro or nanoscale. In this respect, our group has proposed the coupling of electrochemistry to optical microscopies (reflectivity, 3D holography, spectroscopy) in order to allow a complementary monitoring of electrochemistry of local interfacial processes. Such coupled approaches define powerful tools to apprehend local electrochemistry up to the in operando visualization of the chemical activity of individual NPs.[2]

FROM COLLOIDAL QUANTUM DOTS TO COLLOIDAL QUANTUM WELL AND HETEROSTRUCTURES
For few years, colloidal Quantum Dots (QDs) have found a mass market application as phosphors in displays. Their optical properties results from their quantum confinement. In the first part of the lecture I will briefly present these NCs and how chemistry allows tuning their shape and size. In the second part of the lecture, I will present 2D nanocrystals. These 2D nanoplatelets (NPLs) exhibit the narrowest photoluminescence signal thanks to an electronic confinement limited to only one dimension (figure 1). The thickness of these NPLs is control at the atomic level, thus producing optical features comparable to those of quantum well. I will briefly present the synthesis of cadmium chalcogenides NPLs and their optical properties. Then I will present two types of heterostructures (figure 2) obtained with these NPLs. When the growth happens in the confined direction, core/shell NPLs are obtained. More originally, when the growth occurs within the NPL plane, core/crown NPLs objects are synthetized. The type I CdSe/CdS core crown NPLs, has demonstrated to be efficient light concentrator. The type II, CdSe/CdTe core/crown NPLs, exhibit bright emission redshifted compare to the absorption. Finally in the last part, I will show how it is possible to extend the covered wavelength range up to the infrared through the synthesis of mercury charcogenides NPLS.

Advanced process development for nanostructured III-V photovoltaic systems
Professor assistant at University of Djibouti for 8 years, I started my PhD in 2014 at Université Paris Sud on cleanroom processes optimization for nanostructured semiconductors investigation and device development. My work mostly concerns photovoltaic systems and in particular III-V nanowires based solar cells (NW-based SC).
Even though a large part of scientific community is focused on pushing the state of art of optoelectronics performances, the technological development and the cost reduction of smart electronics opened the way to new concepts, such as wearable devices and flexible lightening and energy harvesting systems. Regarding flexible photovoltaic devices, the only technology presents in the market nowadays is constituted by organic semiconductors, which suffer from environmental instability (temperature, humidity) and low performances with respect to inorganic active materials. In this context, III-V nanowires can offer a good compromise between energy conversion efficiency and mechanical properties, due to the possibility to be embedded in a passive flexible matrix; moreover, new generation concepts could be implemented, as multi-junction flexible solar cells (figure below). On the way to the market access, two key points are investigated in this research: a) NW-to-NW homogeneity in terms of electrical contacts with a substrate or a flexible contact, which strongly depends on the cleanroom processes from the as-grown samples to the final device; and b) the development of efficient process steps to handle ultra-thin ( ̴ 1 µm) flexible membranes.

New strategy to modify surface chemistry and morphology of bone filling bioceramics: elaboration of active nanocrystals using supercritical CO2
I am currently carrying on PhD studies related to the setup of a new generation of osteoinductive ceramic biomaterials capable of preventing postoperative infection for bone regeneration. In this work, the treatment of calcium phosphate ceramics with supercritical CO2, in the presence of organic matrix and/or bioactive ions (e.g. Cu2+, Mg2+, Zn2+, Sr2+ ions), induces a remodelling of the mineral framework by way of dissolution/re-precipitation phenomena and the precipitation of carbonated active nanocrystals from added bioactive ions present in supercritical CO2 environment. The characterisation (e.g. by FTIR, XRD, BET, SEM) of the modified scaffolds allows to highlight on one hand the chemical conversion of sintered phases (HA, TCP, HA/TCP) into a poorly crystallized apatite phase similar to bone mineral, and on the other hand a remodelling of the smooth surface with creation of a porosity with nanometric feature due to nanocrystals layout. The introduction, during the treatment, of ionic or molecular bioactive species enables the controlled release of active agents either integrated into the apatitic lattice and/or on the labile surface environment (sustained and medium release), or induces precipitation of bioactive carbonated crystals able by their fast dissolution in biological fluids to induce a rapid therapeutically response (fast release).The final part of this project will consist in introducing an aerogel (based on biocompatible polymer) into the porous ceramic network to allow local absorbtion of fluids and help tailoring of the scaffold’s bioactivity.

Gamma-induced polymerization of P3HT and PEDOT: Application in organic photovoltaic cells
Organic conducting polymers such as poly(3-hexylthiophene), P3HT, and poly(3,4-ethylenedioxythiophene), PEDOT, are characterized by a backbone chain of alternating double- and single-bonds. The duplication of π-bonds along the polymer chains gives remarkable optical and electrical properties, leading to potential applications such as, in photovoltaic cells (OPV), organic transistors and organic light-emitting diodes (OLEDs). In literature, the most common approaches which are used to synthesize conducting polymers (CPs) are either chemical polymerization or electro-polymerization. In our laboratory, we were able to develop a new alternative methodology based on radiation chemistry to synthesize some of those conducting polymers (CPs) in aqueous solutions, thanks to the use of oxidizing or reducing species produced by water radiolysis.
In order to develop a new synthetic method of conducting polymers, to control the optical properties and to tune polymers morphology, polymerization of 3HT and EDOT in several organic solvents by ̴-irradiation was examined. The polymerization was controlled under different environmental conditions (atmosphere, dose and dose rate) and at different monomers concentrations. The radiosynthesized polymers were characterized by using several techniques (attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) and UV-Vis absorption spectroscopy. Their morphology was observed by cryogenic transmission electron microscopy (Cyro-TEM) and scanning electron microscopy (SEM). In a further step of this work, the radiosynthesized polymers (PEDOT doped with Poly (styrene sulfonate), PSS as hole-transporting material and P3HT with [6,6]-phenyl-C61-butyric acid methyl ester, PCBM, as active layer) were incorporated in the fabrication of OPVs devices for photoactivity measurements.

PhD subject: Nano-alloys graphenization: Growth and Properties
The goal of the project is to grow magnetic nano-alloys at the surface (or ideally between two layers) of graphene that is synthetized from the (000-1) face of 6H-Silicon Carbide (SiC). Intercalation would be a good way to isolate nano-alloys from the environment.To grow the system we use cleaning, annealing and evaporation techniques in an Ultra-High Vacuum (UHV) environment.To charaterize this system we use Scanning Tunneling Microscopy and Spectroscopy (STM and STS) along with Magneto-Optic Kerr Effect (MOKE, planned) and classic surface techniques: Low electron Diffraction (LEED) and Auger Electron Spectroscopy (AES).

After graduating from the ESPCI, Ecole Supérieure de Physique et de Chimie de la Ville de Paris, I obtained a master degree at the University Pierre and Marie Curie, Paris.PhD student since October 2016, I am currently working on protein imprinted polymer modified nanoparticles for specific targeting inside cells.
During this summer school, I will present my most recent work on surface-initiated synthesis of bulk-imprinted magnetic polymer for protein recognition. I will speak about a novel synthetic pathway combining bulk and grafting approaches of polymerization to obtain magnetic bovine serum albumin (BSA) imprinted polymer nanoparticles, a protein widely used to develop synthesis pathways. The hydrogen bonds between BSA and acrylamide monomers allow the formation of a pre-polymerization complex and a bulk approach. The complexation of maghemite nanoparticles through an iniferter agent (INItiation – TransFER – TERminaison agent) allows the grafting of the polymer matrix from the surface of nanoparticles. The presence of polymer coatings was assessed through measurements of relaxation times, FTIR and TGA analysis. The adsorption property of the resultant PIP was demonstrated by rebinding experiments. The prepared γ-Fe2O3@PIP nanoparticles present very high adsorption capacities and specificities toward BSA.

In September 2013he moved to Lyon, France, where he starts his second Master, Nanoscale Engineering fromLyon University. During his second Master, he has chosen to do his internships in the field ofbiosensors in laboratories in Lyon and Paris. Starting October 2015, he starts his PhD thesiswith the title “Diamond photonic crystal label-free biosensor” in C2N laboratory. The aim of this thesis is to design and fabricate a new type of optical label-free biosensor on diamond. Diamond is an attractive material due to its optical properties. Also, the diamond surface can befunctionalized especially by covalent bondings, for creating biological layers extremely stableand selective, an interesting property for an optical biosensor. Fabrication of optical micro- andnano-structures in diamond, especially of photonic crystals, lead to the light confinement and to the sensitivity of refractive index change on their surface. The thesis addresses the modelization and numerical simulation (FDTD, plane wave) in order to determine the geometrical parameters for structures for working in the visible wave range. The fabrication part starts with diamond growth by Microwave Plasma assisted Chemical Vapour Deposition.
The following processes of biosensor fabrication are done in clean-room facilities, including surface planarization of diamond, plasma etching by Inductively Coupled Plasma, wafer bonding and electronic lithography.Optical characterization of the photonic crystals is realized by a laser and a detection camera, where the reflection spectrum of the photonic crystal is measured. Optical properties of the structure are analysed and also the detection in different environments (gas or liquid).

PhD Title: Optical control of spin properties and valley indices in semiconductor nanos-tructuresPhD Supervisors: Bernhard Urbaszek and Pierre Renucci
I am working on 2D materials and especially Transition Metal Dichalcogenides (TMDC). These materials are particularly studied for their optical properties since 2010 when it has been shown that contrarily to the bulk material, TMDC monolayers have a direct bandgap in the visible range. Furthermore, light-matter interactions in these monolayers are governed by robust excitons (tightly bound electron-hole pairs) and interesting valley-selective optical selection rules.
Under the supervision of Dr. Cédric Robert, I have worked intensively on sample fabrication using an improved exfoliation technique with PDMS stamps to perform deterministic transfers of TMDC monolayers and to fabricate van der Waals heterostructures by superimposing different thin materials which are stacked together by van der Waals forces. Hence, we can change the dielectric environment surrounding the TMDC monolayers to modulate excitonic transitions and affect quantities such as the exciton or trion (charged exciton) binding energies. For instance, encapsulation of 2D TMDC into thin layers of hexagonal boron nitride has greatly improved the quality of our spectroscopic measurements by reducing the excitonic transitions linewidth, thus approaching the homogeneous limit (<2meV). I also fabricated more complex heterostructures such as charge tunable devices to dope monolayers, which enabled our team to access both positive and negative trions, and even to distinguish a fine splitting of 6meV corresponding to the energy difference between the intravalley and intervalley negative trions.
Generally, to analyze these samples, optical spectroscopic measurements, such as Photoluminescence and Reflectivity, are performed at temperatures as low as 4K.

The last years have seen a growing interest in the research and characterization of 2D materials, due to their interesting and exotic properties. In particular, for free-standing silicene, the 2D allotrope of silicium, DFT simulations predicts the existence of Dirac cones in the electronic structure. This makes silicene an appealing candidate for microelectronic devices. Experimentally, 2D Si arrangements have been reported on several substrates, among which Ag(111) is by far the most thoroughly studied. Silver was thought to weakly interact with the Si sheet; however joint experimental studies and DFT simulations have shown a non-negligible interaction. In order to decouple the Si layer from the Ag substrate, researchers have tried to synthetize multi-layer silicene. The structure of the films obtained is however highly controversial.
Thanks to thorough experimental studies supported by DFT simulations we managed to identify the structure of the 4x4 phase of silicon monolayer on Ag(111) and to solve the controversy on the so-called “silicene multi-layer”. In particular, above 1ML Si deposition, the film obtained has the properties of diamond bulklike silicon with evidences of Ag atoms reconstructing at the surface. Thanks to thermodynamic considerations and real-time microscopy studies we have also discovered a “surfactant competition” of Si and Ag.

In-depth in vivo pH imaging using SWIR-emitting nanocrystals
Solid tumors have an acidic extracellular pH that enhances tumor growth and causesresistance to therapy. pH imaging therefore fulfills an important need in cancer imaging.Fluorescence imaging is a versatile, functional and non-invasive imaging modality but is limited in depth due to diffusion and absorption of light by tissues. Compared to currently usedwavelength ranges, short wave infrared (SWIR, 0.9-1.7 μm) enables much higher (> mm)penetration depths with sub-cellular resolution. However this range remains unused due to thelack of SWIR organic fluorescent probes.
In this project we develop inorganic SWIR nanocrystals (quantum dots QD) to fulfill thisneed, functionalize them for in vivo imaging and make them sensitive to the pH in theirenvironment. To this end we will improve existing syntheses of SWIR nanocrystals based onsilver chalcogenides or lead chalcogenides by growing a passivating ZnS shell. We will thencoat these nanoprobes with zwitterionic polymers to provide both the biocompatibility and thestable colloidal suspension. In addition, we develop pH-sensitive polymers in order to obtain afluctuating fluorescence depending on the pH. This pH-sensitive polymers is end-functionalized with gold nanoclusters that enable to modulate the QD–to-gold quenching efficiency and image

I am in the first year of my PhD, in the Groupe de Physique des Matériaux (GPM), Université de Rouen Normandie, which consists in studying the structure of doped silica based materials for optical applications, using Atom Probe Tomography.

Atom probe analysis of Pr3+ doped hafnium silicate films: phase separation and location of dopants
Hafnium silicate (HfSiOx) are mainly considered as one of the most promising high dieletric material to replace SiO2 in complementary metal-oxide semiconductor technology. This can be ascribe to their good thermal and chemical stability on Si wafer, their wide optical band gap and their high refractive index. Besides, due to their lower phonon frequencies compared to SiO2, these HfSiOx matrices are expected to be a suitable hosts for rare-earth (RE) activators.
Recently, the luminescence of Pr3+ ions, in the visible range, was observed in Pr-doped HfSiOx layer elaborated by magnetron sputtering. The maximum of luminescence intensity was obtained for a 1,000°C annealing and the signal was attributed to an efficient excitation by oxygen vacancies located in a HfO2 phase. In fact, it is known that, in such matrices, a phase decomposition can occurs between SiO2 and HfO2 at high temperature, nevertheless, this decomposition depends strongly on the condition of elaboration and could be slightly different for a doped material.
The Atom Probe Tomography was used to observe and quantify this phase decomposition upon annealing on Pr-doped HfSiOx, in order to get a precise reconstruction of the nanostructure of the thin layer. In fact, the knowledge of an accurate atomic structure of the hosting material and particularly the local environment of Pr3+ ions, can be important in order to improve and optimize new RE-based photonic devices.

44Key words : semiconductors, silicon photonics, laser source, Germanium
I am an engineer graduated from the “Institut d’Optique Graduate School”, in Palaiseau. I have also obtained in parallel a Master 2 in Nanosciences, from the “Université Paris-Saclay”. My main areas of scientific interest are around optics and photonics applied in nanoscience.
I am currently a 2nd year PhD student, working in the “Centre de Nanosciences et Nanotechnologies – Orsay”, in collaboration with STMicroelectronics (CIFRE grant). The title of my thesis is: “Direct band gap group IV semiconductors for a silicon photonics laser source”. The main goal is to realize a Germanium laser for a monolithic integration of a laser source on silicon chips.
The Si-based optical platform is rapidly changing the landscape of photonics by offering powerful solutions, for example in data links (optical interconnects), sensing…Nowadays, III-V group materials are implemented to integrate active light sources on the Si platform, but because of their chemical intolerance to Si, their integration bears a lot of burdens which raises the fabrication costs. That is why realize a monolithic-integrated laser source with direct band gap IV material (fully compatible with Si) would be a paradigm change for Si-photonics. Germanium, as a group IV element, is an ideal candidate.
We use strain engineering, supported by band structure modeling to change Ge into a direct band gap semiconductor. This allows to drastically improve the radiative efficiency in germanium.. We develop technology process in the clean room to apply tensile strain to germanium using predefine design of µ-cavities to realize optical feedback needed for laser operation. In the future we will use alloying of Ge with tin to improve the laser performance.

Key words : electron spin decoherence, electrons bound to donors, decoherence mechanisms, spin qubit.
My name is Guadalupe Garcia Arellano, I got my bachelors’ degree and master degree in Physics at the Benemerita Universidad Autonoma de Puebla in Mexico. Nowadays, I am a PhD student at the Institut of Nanosciences in Paris. My thesis subject is entitled Dopants in nanostructures electron spin decoherence and spin entanglement. The aim of this PhD project is to expand the knowledge and achievements developed during last years in the field of single trapped atoms or ions to dopants immerged in semiconductor nanostructures. We specifically study the spin decoherence and spin entanglement of electrons bound to donors in semiconductor heterostructures. For this purpose, we work with a pump-probe experimental technique that uses laser pico/femtosecond and allows reading the optical spin information previously written in the sample by a pump beam. We focus, in particular, on the creation of coherent superposition of states of electron spin and on the study of their time-evolution. The principal goal is to understand the decoherence mechanisms operating in the system and possible schemes of manipulation of a spin qubit and entanglement or two spin qubits.Single dopant atoms are now becoming increasingly important and researched, not only for classical electronics but also in the field of quantum information, because of this, my current plans are to continue my research in this area and also learning more about new quantum systems and new quantum technologies.
I consider that Nanosciences is an area with great technological impact that currently offers one of the best opportunities for physical involvement. That is why I decided to apply for this program. I would like to learn about nanotechnologies for the future and also on the application of nanosciences in areas such as sustainability, chemistry and biology.

47Key words : Nanosensors, gold nanoparticles, DNA origamis
I’m currently finishing a five-year program at EPF, a multidisciplinary engineering school. During my fourth and fifth years, I spent two semesters at Polytechnique Montréal in Canada to specialize myself in biotechnology and medical sciences. I did a first internship in Neurosciences in the group of Prof. Christian Casanova. In a second internship, I discovered how nanotechnology could be used for biomedical applications in the group of Prof. L’Hocine Yahia. In particular, I worked on the design of superparamagnetic iron oxide nanoparticles to control the release of nitric oxide in order to treat nosocomial infections.
In order to discover further the applications of nanosciences in biotechnology, I started in January an internship at Institut Langevin (Paris) with Dr. Sébastien Bidault, to work on the design and characterization of optical nanosensors based on gold nanoparticles and DNA origamis. The aim of this project is to allow the colorimetric detection of single molecules on a simple colour camera. We work in collaboration with Dr. Gaëtan Bellot from IGF in Montpellier who designs and synthesizes dynamic DNA origamis that are sensitive to specific stimuli.
At the end of my internship, I hope to continue this project during a PhD. Indeed, I am particularly interested by the interface between nanosciences and biotechnology. Furthermore, the potential applications in medical diagnostics are very motivating.

Control of magnetic domain wall nucleation and propagation by Helium focused ion beam irradiation.
Light ion irradiation is a well-known technique for tailoring the properties of ultrathin magnetic films. In the case of Pt/Co/Pt layers, Helium irradiation at low energy allows to adjust locally the perpendicular anisotropy, leading to the control of both nucleation and transport properties of domain walls. The particularity of the focused ion beam irradiation technique is its very fine control of the fluence delivered (around 1 ion/nm²) and its spatial resolution (of the order of 10 nm), together with relatively swift execution times compared to irradiation through a mask.
We aim to control the nucleation and the propagation properties of domain walls in Pt/Co(0.7nm)/Pt, studied by polar magneto-optical Kerr effect microscopy. The irradiation at fluences sufficient to annihilate the out-of-plane component of magnetization (around 200 ions/nm²) of small regions give them the property of nucleating domains at low field (30 mT) and of strongly pinning domain walls due to a large gradient of anisotropy. With focused ion beam irradiation, it is also possible to pattern the fluence delivered at the scale of a few 10 nm. This length is of the order of the Larkin length in Pt/Co/Pt and could lead to a local control of domain wall pinning.

Tobias Lange was born in 1990. He obtained his Master degree in chemistry from Universität Regensburg (Germany) in 2015. In 2016 he started his PhD thesis at the CEA.
Title: Controlled Reactant Feeding by Composite inorganic/organic Nano Tubes
Emulsion precipitation can be implemented on a large scale through the use of pulsed columns, which disperse large quantities of aqueous phase in the form of droplets in an organic phase. Precipitation occurs after coalescence of two drops each containing two different reactants. If the feasibility of such a process for the usage in nuclear waste treatment is proven, partial knowledge of the reaction mechanism is a limiting step.Deeper understanding of the mixing and feeding of reactants is necessary for a better control of the precipitation step. One strategy to control the reactant feeding is to avoid coalescence of the droplets and transport the reactants by other means.To realize the transport, we chose to investigate on a nano sized tubular clay named imogolite with the following chemical composition: Al2O3∙SiO2∙2H2O. After modification of the outer tube surface it is able to stabilize droplets through the formation of a Pickering emulsion and could transport reactants through their inner cavity from one droplet to another.We found that the tube modification is in competition with tube destruction. First, we investigated on the modification parameters by WAXS, IR and MAS NMR analyses. Then, to investigate on the feasibility of the reactant transfer, conductivity measurements were used to observe feeding through a self-assembled membrane of modified imogolite.

I have obtained engineer’s degree at Wrocław University of Technology in Poland in 2015. The same year my Monabiphot Erasmus Mundus program has been completed with thesis written under supervision of Claude Nogues and Bruno Palpant. From September 2015 I have joined a PhD program in “Structure et dynamique des systèmes vivants” (SDVS) doctoral school with subject ”Light induced thermal energy conversion of gold nanorods applied to gene therapy” co-supervised by Claude Nogues (LBPA laboratory) and Bruno Palpant (LPQM laboratory).
Interactions between single-strand DNA and hexadecyltrimethylammonium bromide (CTAB) in gold nanorods (GNRs) research
Gold nanorods (GNRs), due to their extraordinary optical properties, receive a large amount of attention focused on their use in targeted therapies, like gene delivery. By changing synthesis conditions it is possible to obtain particles with absorption maximum in the near-infrared (NIR) range matching the requirements for medical applications. Illumination by NIR laser causes the conversion of light into thermal energy and therefore an increase in temperature around the GNRs. This phenomenon can be used for controlled release of drugs, however preparation of functionalized materials requires detailed knowledge about surface chemistry. The disadvantage for usage of this nanoparticles is the synthesis method which includes CTAB, which is difficult to remove from gold surface. The aim of this project is to understand CTAB-ssDNA interactions by observing fluorescence and Forster Resonance Energy Transfer (FRET) over a wide surfactant concentration (from 0 up to 10 mM) in different media. Quenching of the emission intensity of a fluorophore due to the presence of CTAB in solution and the formation of DNA clusters at specific surfactant concentration are also characterized.

TRAVAIL DE THÈSE
INTERACTION MOLÉCULE-SURFACE PAR SPECTROSCOPIE DE REFLEXION SELEC-TIVE
Le but de mon travail est de mesurer les effets de l’interaction du type van der Waals (ou Casimir-Polder) entre une surface et une molécule à sa proximité. Il existe bel et bien une interaction entre des particules à proximité d’une surface et les études de l’interaction atome-surface l’ont déjà mise en avant. Elle est décrite par un potentiel de type f(z)/z3 où z est la distance entre la particule et la surface. Selon les régimes de distance, elle devient –C3/z3 où C3 est le coefficient de van der Waals qui dépend de la surface. L’aspect novateur de mon projet réside dans le fait qu’on cherche à mettre en évidence l’interaction molécule-surface et par la même, dire en quoi elle se distingue de celle qu’il y a avec les atomes, si c’est le cas.Techniquement, on utilise la spectroscopie par Réflexion Sélective pour la mesurer. Cette spectroscopie a l’avantage, en plus d’être linéaire et de haute résolution en fréquence, de nous permettre de sonder un petit volume du milieu étudié (gaz), dont l’épaisseur sondée est de l’ordre de la longueur d’onde du laser de mesure. Nous avons choisi de travailler avec des molécules (SF6 et NH3) qui ont des transitions dans l’infra-rouge à 10,6 µm. Etant inversement proportionnelle au cube de la distance, nous avons la difficulté de devoir mesurer un potentiel beaucoup plus petit que celui que l’on obtient lorsque l’on utilise des atomes qui ont des transitions électroniques à des longueur d’onde de l’ordre de la centaine de nanomètres. Nous avons néanmoins obtenu des signaux prometteurs de Réflexion Sélective qui nous laissent entrevoir la possibilité de mesurer l’interaction molécule-surface.

Probing structural and electronic properties of Graphene/h-BN heterostructures by STM
The discovery of graphene has opened the field of 2D materials and particular attention has focused on their stacking due to unique properties and potential applications.[1] It has been shown that the transport properties of exfoliated graphene supported by hexagonal boron nitride (h-BN) could approach the intrinsic properties of graphene.[2] Studying the structural properties of 2D materials and 2D heterostructures is crucial to understand their physical and chemical properties. Scanning tunneling microscopy (STM) and scanning tunneling spectroscopy (STS) at 4K can be used to probe the structure and electronic properties of graphene, h-BN heterostructures. The capping of h-BN by a graphene layer allows to probe the defects of bulk h-BN with STM. In particular native defects can be probe as the electric field applied by the tip can induce their ionization that is detected in the tunneling current as it was shown in the literature [3].
Here we have studied graphene on h-BN (G/h-N) and nitrogen doped graphene on h-BN (NG/h-BN) heterostructures. We have detected h-BN defects through the graphene layer capping h-BN, some of these defects exhibit ring-like features whose size rely critically on the tunneling condition as they arise from tip induced electric field (Figure 1). Our data show that the defects induced by nitrogen doping in NG/h-BN heterostructures exhibit different characteristic from the native defects in G/h-BN as it will be discussed.

I was particularly interested in the synthesis of new NIR organic (voltage sensitive dyes) and inorganic (silver chalcogenide quantum dots) emitters for in vivo fluorescence imaging. More recently, I also worked on the synthesis of novel metal-phosphorus-boron nanoalloys using both red and white phosphorus as phosphorus donors. For my Ph.D. thesis, I am currently working on a new nanomaterials design approach that takes into account the product’s toxicity.
“Bimetallic oxysulfide nanoparticles: towards a Safe-by-Design approach”Nanoscience, as an emerging field, has resulted in many manufactured nanoparticles which are already on the market. However, the impact of those nanoparticles on our health has yet to be completely understood. Thus, it is crucial to establish a new design approach that takes into account not only the nanoparticles’ properties and performance but also their potential toxicity.The aim of my thesis is to develop this Safe-by-Design approach for bimetallic oxysulfide nanoparticles which have potential applications in various fields such as bioimaging and photocatalysis. In order to do this, I study the effect of the nanoparticles’ physico-chemical parameters (size, shape, composition, surface state, etc.) on their performance as functional materials as well as their toxicity when in interaction with living organisms.

Phase transition in bi (Pt-Ag) and tri (Co-Pt-Ag) metallic nanoalloys
The nanoalloys’ structural properties are highly complex and very interesting due to their size-dependent evolution. Indeed, metal nanoalloys have different chemical and physical properties compared to their bulk matter counterpart, due to the size reduction.Concerning the bi metallic (Pt-Ag) system, the bulk phase diagram is complex and interesting. At low temperature, an ordered alloy is evidenced only at the equi-stoichiometry and there is a quasi-complete immiscibility for the rich-Pt part and a partial immiscibility for the rich-Ag part. The objective is to experimentally determine if the alloy phase could exist at the nanoscale or if the segregation phase dominates due to the surface effect and the size reduction. Another objective is to study the reactivity of these particles with different size, phase and composition, especially in oxygen environment.Concerning the tri metallic (Co-Pt-Ag) system, the interesting phase is the L10 phase of CoPt nanoparticles due to its magnetic properties. However, in order to obtain the L10 phase in CoPt nanoparticles, the sample has to be annealed at least at 700°C.We propose to study the ordering mechanisms in the case of the present of a dopant (Ag). Indeed, Ag has a strong tendency to segregate at the nanoparticles surface in the CoAg and AgPt system, but Ag could also form an ordered phase with Pt. We can expect that all these mechanisms increase the internal atomic mobility and consequently lower the disordered/ordered transition temperature of the CoPt system.
In order to investigate structures and chemical configuration of such nanoparticles, HRTEM, STEM-HAADF (Z-contrast) and in situ X ray scattering have been performed.
Our final goal is to establish a phase diagram at the nanoscale for Pt-Co-Ag system.

Currently a PhD student working on Magnetic tunnel junctions made with organic self-assem-bled monolayers.
Magnetic tunnel junctions are devices made of two ferromagnetic electrodes separated with an insulating layer. Depending on the applied field, the magnetization of the electrodes can be parallel or antiparallel, modifying the resistance of the device. Our group focuses on replacing the insulating spacer, usually made of an oxide thin film, with an organic self-assembled monolayer. Previous works were done with basic molecules such as linear alkanethiols. We now focus on more complex molecules (integrating aromatic moieties for instance) to study how the modification of the tunnel barrier electronic structure impacts the spin-dependent transport properties of the devices.

Design of molecular building-blocks for original nano-structured hybrid silica: Applica-tion in catalysis
Silica-based hybrid materials were investigated for many applications, ranging from optical application (e.g. micro-lenses) to health domains (e.g. drug carriers/delivery and implants).[1] In particular, the incorporation of metal cations in organized silica-based network was essential to the design of supported catalysts.[2]Silica-based matrices exhibit tunable mechanical properties, thermal stability and porosity. For the construction of 2D and 3D architectures, several families are studied, such as bridged silsesquioxanes, polyhedral oligomeric silsesquioxanes/siloxanes (POSS/POS) and lamellar silica.[3]
My work consists in developing 2D and 3D nanostructured hybrid materials that will be conceived by connecting functional organosilane linkers onto layered silicas and POSS/POS respectively. The linkers can be urea-thiourea[4], malonamide or bi-pirydine units. Each of them can play a double role:- self-assembly through molecular interactions (e.g. H-bonds, ̴-stacking, and Van der Walls)- metal insertion (e.g. Ag, Cu Au,etc… ) through complexing site that will thus result in a new type of supported catalyst.

Title: Local sources of thermoelectric energy
Thermoelectric materials allow building energy harvesting or cooling device with no moving part. Nowadays, thermoelectric performances (linked to the zT parameter [1]) and coupling to a real environment [2] are the main issues. A simple, accurate and robust method to properly evaluate obtained properties in both cases is still needed. For a complete characterization, the figure of merit ( ) is obtained with independent measurements of the Seebeck coefficient (α), the electrical conductivity (σ) and the thermal conductivity (̴), T being considered as the mean temperature.
Impedance spectroscopy is a simple electrical measurement which was initiated by S. Dilhaire et al. [3] for thermoelectric material allows for the complete characterization of all thermoelectric properties. This method is based on the separation between slow processes (that only appear at low frequency, such as thermal processes) and fast processes (electrical response) as a system is submitted to an alternative current.
Following this track, we have been able to apply the impedance spectroscopy technique from single materials to complete devices. Coupling an analytical model with experimental results on different systems, the main parameters are extracted allowing quantitative measurement of constitutive materials. The method also gives access to the coupling parameters with environment.

I graduated from the Pierre and Marie Curie University with double major physics and chemistry. I have a master degree on molecular chemistry, specialized on nanosciences.As part of my master, I worked, on the Laboratoire de Chimie Inorganique, at the Paris-Saclay University, on nanomagnetics core-shell of Prussian Blue analogues to study the impact of the shell isomerization on the core magnetic properties. We expected a magnetic (high spin to low spin) and optic transition with the temperature. Then, I studied, during my master internship, the hydrocraquing of n-heptane with Pt loaded nano-heterostructures zeolite/γ-Al2O3 with metal nanoparticles selectively deposited inside the zeolite or on the alumina part.
Microwave continuous flow coupled with a UV source synthesis of gold-oxide nano-heterostructures for catalysis and photocatalysis applications
The first goal of my PhD project is to understand the impact of microwave assisted heating on nucleation and growth of oxide nanoparticles and more specifically the opportunity to form anisotropic nanomaterials. In situ characterizations, such as synchrotron X-ray Absorption Spectroscopy and Small Angle X-ray Scattering, are necessary to elucidate different steps during the reaction. A comparison between batch and continuous flow synthesis will be carried out. Then, a one-pot protocol, combining microwave heating and light irradiation, will be developed to prepare metal-oxide catalysts. These materials will be validated during catalytic test of CO oxidation and photo-degradation of rhodamine B, phenol and formic acid.

Key words : Alumina, nanorods, hydrothermal synthesis, microwave synthesis, catalysis, nanomaterial processing.
Graduated from the Pierre et Marie Curie University in Chemistry major. I have a master’s degree in inorganic materials specialization.
During my bachelor I was part of an internship called «Zinc oxide nanoparticles elaboration for photovoltaic applications». The aim of the project was to tune ZnO nanoparticles to obtain particles which absorb UV light and emit a light around 600 nm.During my master’s degree I was involved in two internships on Metal Organic Frameworks. The first one on «Metal-organic frameworks hybrid materials for the selective N-aromatic compounds capture». In order to obtain N-selective materials, we tried to understand the different interactions between molecules, metal and ligand by using different kind of reported MOF. The second one was on « Metal-organic framework adsorbent materials study for selective gas separation ». The objective was the separation of gases using reported and non-reported MOFs.
Currently, I’m a PhD student in the «Laboratoire de Chimie de la Matière Condensée de Paris» in collaboration with the IFPEn. I’m working on «Control of alumina textural properties by nanorods morphology and organization». Alumina nanoparticles is a commonly used catalytic support in the industry. Literature shows that their exposed faces and the reactants’ diffusion are key parameters in heterogeneous catalysis. Thus, surface area and pore volume are critical parameters for my project. The aim of this project is to synthesize nanoparticles with new morphology hence new properties. For example, resulting different exposed faces could lead to new catalytic reactions. Moreover, processing of the obtained alumina nanoparticles will be done and the final product will be studied in order to prove the anisotropic nanomaterials’ appeal for catalysis at industrial scale.

63Key words : Inorganic nanoparticles, biotransformation, biodegradation, ferritin.
I am a third year PhD student in the PIF doctoral school. Chemist by training (Magistère de Physico-chimie Moléculaire, Université Paris Sud, Master Physico-chimie des Matériaux, Université Paris 6), I joined the MSC lab for a project at the interface of chemistry, physics and biology. My PhD projects aims to understand the biodegradation and the long term fate of inorganic nanoparticles in vivo. Inorganic nanoparticles such as gold nanoparticles or iron oxide nanoparticles are widely used for their significant potential in theranostics (contrast agent for MRI, activator for controlled drug release, local heaters for tumor ablation…). Although the potential toxicity of such nanomaterials are extensively studied, their long term fate,their biodegradation and biotransformation are still poorly understood.
We propose a multi-scale approach to study the life cycle of metal oxide nanoparticles in biological environment based on the evolution of their physical and morphological properties. We first developed a modelisation of NPs degradation in vitro in a simple medium mimicking the biological environement to evaluate and compare the transformation of different types of inorganic NPs (composition, coating, size..). Then we aimed to decipher the processing of NPs by endogenous iron storage protein, the ferritin.

I graduated my studies in faculties of chemistry (Ist degree) and technical physics (IInd degree) in University of Technology in Wroclaw. During this time I participated in different theoretical and experimental projects like “Characterization of CTAB conformation in water solution in the presence of different force field” and “Light induced particle organization in paramagnetic fields”, respectively. I also was a co-organizer of two editions of WAMMBAT (Workshop of Atomistic and Mesoscale Modelling in Bio-Applications and Technology) and co-writer of workshop book Multiscale modeling in biotechnology and nanoengineering: from experiment to simulation and back again with L. Radosinski, K. Labus, A. Olejniczak, F. Formalik, M. Achremowicz, J. Rogacka and M. Talma in Wroclaw. My engineer and master thesis had molecular modelling background. During engineer thesis I was working on Monte Carlo simulations of hydrogen on graphite surface to describe adsorption phenomena. My master thesis was about transport of molecules through silica membrane and description of diffusion process through this structure by using Molecular Dynamics simulations.
Currently I am second year PhD student and I am working on carbon hybrid nano-porous structures to enhance hydrogen storage (HYSTOR project). In this project we explore the potential effectiveness of arc-discharge procedure to synthesize nanoporous, carbon based sorbents with characteristics required in vehicular applications. Nanostructures are characterized in term of texture using nitrogen adsorption measurements while the boron distribution is followed using energy filtered transmission electron microscopy.

* The title of PhD project: Conducting Polymer Nanostructures for Photocatalysis under UV and Visible Light
Visible-light responsive photocatalysts can directly harvest energy from solar light offering a desirable way to solve energy and environment issues. Conducting polymer nanostructures emerge as a new class of photocatalysts very active under visible light. Polyprrole (PPy), as a conjugated polymer, exhibits a wide range of applications. We present here the first illustration of employing pure PPy nanostructures as a very efficient photocatalyst for the depollution of water. PPy was synthesized in soft template by chemical polymerization (PPy-c), obtained by radiolysis (PPy-γ), and synthesized without template via chemical method (PPy-bulk) as bulk. Among these three samples, PPy-c shows the best photocatalytic performance under UV light, while PPy-γ exhibits the highest activity for phenol degradation under Visible light. However, PPy-bulk presents very weak photocatalytic activity under UV and Visible light. The photocatalytic mechanism of PPy was studied. These samples have been characterized by SEM, TEM, NanoIR, FTIR, UV-Vis spectroscopy. The conductivity and the electrochemistry performance of PPy nanostructures were also researched.

My physics group FINANO (Films minces, matériaux fonctionnels et nanostructures) of the LSPM Laboratory of Paris 13 University (France) has a standing experience concerning the Brillouin light scattering (BLS) and Micro-strip line Ferromagnetic (MS-FMR) spectroscopies. The BLS technique, which analyses inelastic light scattering with frequency shifts lying approximately in the [1-100] GHz interval, allows investigation of the dynamics of elastic and magnetic properties in the frequency range. In contrast to the conventional FMR, the MS-FMR allows dynamic measurements over a large frequency range (2-18 GHz).

My post-doctoral studies in LBNL were dedicated to advanced characterization of Li-on battery materials using in situ spectroscopies, scanning probe microscopies and near-field spectroscopy (NanoIR) to understand the slow but inleuctable degradation of electrode materials under operation.
My current researches focus on the development of Raman spectroscopy at the molecular scale (TERS) associated with electrochemistry techniques for the characterization of advanced materials (colloids, materials for energy storage, nano-microelectronics).
Teaching activities: lectures in thermodynamics, electrochemistry, spectroscopy (bachelor of chemistry L-2, L-3: UPMC), in general chemistry for medical school students (PACES, UPMC) and high school teachers («CAPES», «agregation interne»).

My research activities are focused on the design of functional nanomaterials through chemical molecular approaches.
I performed my PhD research between 2005 and 2008 in the Lab. of Chimie de la Matière Condensée de Paris (LCMCP), under the supervision of Prof. J.-P. Jolivet, on the aqueous soft chemistry synthesis of manganese oxide nanoparticles. I moved to Germany from 2008 to 2010 for a postdoc in the Max Planck Institute for Colloids and Interfaces where I started to develop new synthetic approaches for the design of nanomaterials which are somehow “exotic” to the chemist community, namely crystalline substoichiometric titanium oxides, boron carbon nitrides and metal borides. Advanced properties were investigated in fields such as thermoelectricity, hydrogen storage and visible-light fluorescence.I became CNRS research associate in 2010 in the LCMCP in the group of Prof. C. Clément Sanchez at the Collège de France (Paris). My current interests are twofold. On one side, I develop innovative strategies to tune heterogeneity at the nanoscale, which implies for instance the design of multi-compartment inorganic and hybrid nanoparticles, and of nanocomposites for the emergence of novel properties for energy storage and conversion, environment and information technologies. On the other side, I set advanced methodologies for reaching uncommon inorganic compositions, such as multicationic oxides or boron-based systems, which are especially difficult to obtain at the nanoscale by solvent-mediated approaches.

Vincent Repain is working in the «Self-organization» of nanostructures and STM» group inside the Quantum Materials and Phenomena Laboratory of the Paris Diderot University. The research of the STM team is devoted to the study of materials at the nanometer scale on surfaces.
Its scientific interests are very broad, going from the fundamental structure of surfaces to the magnetic and electronic properties of nano-objects. Experimental techniques are mainly scanning tunnelling microscopy (STM) and X-ray surface diffraction under ultra-high vacuum. The goal is to study and understand the fundamental properties of matter down to the Atomic scale, linking a structural analysis with the measurement of the electronic density of states and magnetism. A comparison with simulations or theoretical tools developed in the team or through collaborations is systematically performed in order to extract the underlying physics in the studied phenomena. In particular, our long-term experience in the realization of state-of-the-art samples using self organization on crystalline surfaces allows us to give new insights in the field of nanomagnetism at a challenging scale.
